- POST /v1/csp collects browser CSP reports in both wire formats (legacy application/csp-report and Reporting API application/reports+json), with CORS limited to the operator's domains (any subdomain of k6n.net, tornberg.me, knatofs.se) and preflight handling. - Reports are stored in a dedicated typed ClickHouse table (csp_reports, 90-day TTL) with a JSONL file fallback (OTEL_CSP_PATH). - New authenticated view endpoints /api/csp/reports and /api/csp/summary plus a 'CSP reports' screen in the UI (tab 12) with time window, site and directive filters and report drill-down. - Documented in instrumentation.md; unit tests for parsing/handlers/file store and an env-gated ClickHouse integration test.
